Looped network protection protocol switching time automatic testing method, equipment and system

Abstract

The invention discloses a looped network protection protocol switching time automatic testing method, equipment and system. The method comprises the following steps: configuring networking equipment in a looped network according to a protocol to be tested in order that the networking equipment in the looped network is communicated with one another according to the protocol to be tested; and executing a switching or back-switching operation on the looped network equipment, and calculating a switching or back-switching time according to a difference between quantities of data packets received and transmitted within a set time after switch-off or switch-on of a port and a set data packet transmission rate. According to the automatic testing method, equipment and system, a communication with switch equipment is controlled through an automatic program, the switch-on and switch-off of the port are executed according a control instruction, and a switching time is calculated with a method of calculating a packet loss number, thereby increasing the working efficiency. On the other hand, the automatic testing method, equipment and system can adapt to various switches and various looped network protection protocols; the protocol to be tested and test times can be specified automatically as required to perform testing; and higher test flexibility is achieved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, device and system for automatic testing of switching time of a ring network protection protocol. Background technique [0002] Whether it is an enterprise or a communication operator, the loop problem has always been one of the main problems that lead to network quality degradation or even paralysis. The lack of information flow has brought economic losses to many units. [0003] The formation of all loops is caused by the confusion caused by the ambiguity of the destination path. Network loops cause network turbulence, cause data packets to enter black holes, cause packet loss, and seriously cause network paralysis. Among the current network failures, link and equipment failures lead to the degradation of network communication quality. Usually, network loop failures are also caused by improper path settings during network deployment and rectification. Due to the prevalence ...

Problems solved by technology

[0002] Whether it is an enterprise or a communication operator, the loop problem has always been one of the main problems that lead to network quality degradation or even paralysis. The lack of smooth information has brought economic losses to many units.

Layer 2 loops will cause layer 2 multicast or broadcast packet storms

However, this solution needs repeated verification many times to obtain the average switchover time of the switch, and requires manual operation and calculation, which takes a long time and has low work efficiency
